Ecole Polytechnique Fédérale de Lausanne A colloid is a substance spread out evenly inside another substance. Everyday examples include milk, styrofoam, hair sprays, paints, shaving foam, gels and even dust, mud and fog. One of the most interesting properties of colloids is their ability to self-assemble — to aggregate spontaneously into well-defined structures, driven by nothing but local interactions between the colloid's particles. Self-assembly has been...

Light-Carved ‘Nano-Volcanoes’ Could Help With New Drug Delivery Technologies
2013-06-13 14:37:12

North Carolina State University Researchers from North Carolina State University have developed a method for creating “nano-volcanoes” by shining various colors of light through a nanoscale “crystal ball” made of a synthetic polymer. These nano-volcanoes can store precise amounts of other materials and hold promise for new drug-delivery technologies. The researchers create the nano-volcanoes by placing spherical, transparent polymer nanoparticles directly onto...

Polymer Structures Serve As 'Nanoreactors' For Producing Nanocrystals With Uniform Sizes, Shapes
2013-06-12 14:09:01

Georgia Institute of Technology Tiny chemistry Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures — including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal...

Toolbox For Nanoparticle Manipulation Expanded With New Microfluidic Method
2013-06-06 14:03:40

University of Illinois at Urbana-Champaign Researchers at the University of Illinois at Urbana-Champaign have developed a new flow-based method for manipulating and confining single particles in free solution, a process that will help address current challenges faced by nanoscientists and engineers. “This method is a first-of-its-kind tool for manipulation and trapping of small nanoparticles in solution,” explained Charles M. Schroeder, an assistant professor in the...

Many solids are produced from melting. Depending on how quickly they cool off, invariably, internal tensile stresses begin to build up. One example are Prince Rupert's Drops, or Dutch tears: you can hit their thick end with a hammer without breaking them while a slight pressure applied to their thin end is enough to shatter the entire tear. The properties of safety or even gorilla glass are determined to a large extent by their internal tensile stresses. However, until now, our understanding...

Big Molecule Models Captured In A Flash
2013-05-28 11:02:32

Lawrence Berkeley National Laboratory To learn how biological molecules like proteins function, scientists must first understand their structures. Almost as important is understanding how the structures change, as molecules in the native state do their jobs. Existing methods for solving structure largely depend on crystallized molecules, and the shapes of more than 80,000 proteins in a static state have been solved this way. The majority of the two million proteins in the human body...

A recent study from Stony Brook University examines the presence and effects of gold nanoparticles that are found in everyday items, most notably cosmetics. Dr. Simon Ourian of Epione Beverly Hills says that he expects further studies will find other nanoparticles responsible for accelerating the visual signs of aging. Los Angeles, California (PRWEB) May 23, 2013 According to a April 18, 2013 Stony Brook University report titled “SBU-Led Study Reveals Nanoparticles Found in Everyday...

Grapefruit Nanoparticles Could Provide New Drug-Delivery Method

redOrbit Staff & Wire Reports - Your Universe Online A special type of nanoparticle created using natural lipids derived from grapefruit could be used as a less toxic way to deliver cancer-fighting medication, antibodies such as proteins, and other substances to patients, according to research published Tuesday in the journal Nature Communications. The subtropical fruit has long been known for its health benefits, but now scientists from the University of Louisville have used them...
